Non‐Fused Ring Acceptors Achieving over 15.6% Efficiency Organic Solar Cell by Long Exciton Diffusion Length of Alloy‐Like Phase and Vertical Phase Separation Induced by Hole Transport Layer (Adv. Energy Mater. 6/2023)

Abstract

Alloy-Like Acceptors Non-fused ring electron acceptors are becoming attractive in organic solar cells due to their low cost and easy synthesis. In article number 2203402, Baomin Xu, Aung Ko Ko Kyaw, and co-workers demonstrate a ternary blend using two in-house designed non-fused ring electron acceptors and a polymer donor to form an alloy-like acceptor and vertical phase separation in the bulk-heterojunction.
